LoRaWAN Soil Moisture Sensor Manufacturer for Smart Irrigation and Agriculture
LoRaWAN Soil Moisture Sensor Manufacturer for Smart Irrigation and Agriculture
Efficient irrigation requires more than opening and closing water valves according to a fixed schedule. Farms, orchards and greenhouses need reliable soil data to determine when irrigation is necessary and how much water should be supplied.
A LoRaWAN soil moisture sensor measures the moisture condition around crop roots and transmits the data over a long-range, low-power wireless network. It enables agricultural operators to monitor distributed fields without installing communication cables or placing a cellular SIM card in every sensor.
Shenzhen Jinshengchang Technology Co., Ltd. provides OEM and ODM development for LoRa and LoRaWAN agricultural devices. A customized solution can combine soil sensors, LoRaWAN gateways, remote valve controllers, a cloud platform, mobile applications and API integration.
What Is a LoRaWAN Soil Moisture Sensor?
A LoRaWAN soil moisture sensor is an agricultural IoT device that collects soil-moisture data and sends it to a gateway using LoRaWAN communication.
Depending on the selected probe, the device can measure:
Volumetric water content
Soil temperature
Electrical conductivity
Soil salinity
Nitrogen, phosphorus and potassium
Ambient temperature and humidity
Device battery voltage
Sensor or probe failure status
The LoRaWAN gateway receives these data packets and forwards them to a network server or IoT platform through 4G, Ethernet or Wi-Fi.
A typical system architecture is:
Soil Sensor → LoRaWAN Node → LoRaWAN Gateway → Network Server → IoT Platform → Web, APP or API
This architecture is suitable for large agricultural areas because multiple sensors can share one gateway. Actual coverage depends on terrain, vegetation, gateway height, antenna design, transmission power and local radio regulations.
Why Use LoRaWAN for Agricultural Soil Monitoring?
Agricultural fields frequently lack stable electricity, broadband or Wi-Fi coverage. A conventional wired monitoring system may require trenching, cables and additional infrastructure across a large area.
LoRaWAN offers several practical advantages.
Long-Range Wireless Communication
LoRaWAN can transmit small sensor data packets over long distances. This makes it suitable for farms, grazing areas, orchards and plantations where monitoring points are widely distributed.
The actual communication distance must be confirmed through an on-site radio survey. Hills, trees, buildings, wet vegetation and an incorrectly positioned gateway can reduce coverage.
Low Power Consumption
A soil-monitoring node usually spends most of its time in sleep mode. It wakes up at a configured interval, reads the sensor, transmits the data and returns to sleep.
This operating model can support extended battery life. Solar charging can also be integrated for remote deployments requiring frequent reporting or year-round operation.
No Individual Cellular SIM Card
The field sensors communicate with a shared LoRaWAN gateway, so an individual cellular subscription is not normally required for every sensor.
If the gateway uses 4G for data backhaul, only the gateway requires a suitable mobile-data connection. This can simplify the management of large sensor networks.
Scalable Field Deployment
A project can start with several monitoring points and later add more sensors, gateways and irrigation zones. Devices can be organized by farm, field, crop, irrigation zone or customer account on the management platform.
Main Applications
Crop Field Irrigation
Sensors installed at representative locations can monitor changes in soil moisture before and after irrigation. The platform can alert operators when readings fall below a configured threshold.
This helps reduce irrigation based solely on visual inspection or fixed schedules.
Orchards and Vineyards
Trees and vines may have different irrigation requirements depending on soil structure, slope, root depth and sunlight exposure. Multiple LoRaWAN sensors can provide data from different blocks of an orchard or vineyard.
Greenhouse Monitoring
A greenhouse can combine soil moisture, soil temperature, air temperature and humidity monitoring. Collected data can support manual irrigation decisions or automatic control rules.
Pasture and Remote Farm Irrigation
Remote pastures may not have access to wired power or fixed internet. Solar-powered sensors and an off-grid LoRaWAN gateway can create a monitoring network in these locations.
Landscaping and Municipal Irrigation
Wireless soil sensors can be installed in parks, road landscaping, gardens, sports fields and other distributed green areas. The system can help maintenance teams identify areas that are too dry or receiving excessive water.
Connecting Soil Sensors to LoRaWAN Smart Valves
A soil moisture sensor provides the data, while a LoRaWAN smart water valve performs the control action.
When these devices are connected through the same platform, the system can support automation such as:
The soil sensor reports a low moisture value.
The platform confirms that the reading remains below the configured threshold.
The system sends an opening command to the appropriate irrigation valve.
Irrigation begins for a defined duration.
The valve closes automatically.
The sensor reports the resulting change in soil moisture.
The platform records the complete irrigation event.
For greater reliability, automation logic should also consider rainfall, water pressure, flow rate, valve feedback and communication status. A single abnormal sensor reading should not immediately trigger irrigation without verification.
Sensor Probe Options
Different soil types and crops require different sensor technologies. A professional project should not select a probe only according to price.
Available integration options may include:
Capacitive soil-moisture probe
FDR soil-moisture probe
TDR soil-moisture probe
Soil moisture and temperature probe
Soil moisture, temperature and EC probe
Multi-depth soil monitoring probe
RS485 Modbus agricultural sensor
Analog voltage or current-output probe
SDI-12 compatible environmental probe
The appropriate measurement range, accuracy and calibration method depend on soil composition, salinity, installation depth and the required application.

Platform and Data Management
A complete soil-monitoring platform can provide:
Live soil-moisture readings
Historical data curves
Field and irrigation-zone management
Minimum and maximum threshold alerts
Low-battery notifications
Offline-device alarms
Gateway status monitoring
Sensor calibration records
User and role management
Web and mobile access
Data export
Multilingual interfaces

Jinshengchang’s lora8 platform can integrate LoRaWAN sensor data, gateway status and remote-control devices into one project interface. Customers may also connect the hardware to their own network server or agricultural management platform.
Gateway Deployment
Gateway placement has a major influence on system reliability. The gateway should generally be installed:
Above surrounding crops and vegetation
Away from large metal structures
In a location with a clear radio path
Inside a suitable weatherproof enclosure
Where 4G, Ethernet or Wi-Fi backhaul is available
With appropriate surge and lightning protection
Large farms may require multiple gateways. Overlapping coverage can reduce communication blind spots and provide additional network resilience.
Before mass deployment, a pilot test should be conducted using the actual sensor height, antenna, frequency band and reporting interval.
Data Accuracy and Installation
Wireless communication does not determine measurement accuracy. Accuracy depends primarily on the probe, calibration, soil conditions and installation method.
For dependable results:
Select a probe suitable for the soil type.
Install it at the crop’s effective root depth.
Ensure good contact between the soil and probe.
Avoid air gaps around the sensing area.
Do not install every sensor near a water outlet.
Compare initial readings with reference measurements.
Recalibrate when moving the probe to a substantially different soil type.
Protect cables and connectors from agricultural machinery and animals.
A single sensor may not represent an entire field. Large or uneven fields should be divided into monitoring zones based on soil type, elevation, crop and irrigation layout.
OEM LoRaWAN Soil Sensor Development
Jinshengchang can customize the complete sensing terminal rather than only supplying a standard communication module.
OEM and ODM services can include:
Sensor selection and interface integration
